摘　　要：冷轧带钢因内部残余应力分布不均造成各种屈曲模态的板形缺陷。求解这一屈曲过程需要构造合理的初始位移函数。另外,板形平直度自动控制也必须依据符合实际的浪形理论。本文用BLD—90激光测距仪精确地实测了冷轧宽带钢生产中出现的各种浪形,经最小二乘曲面拟合分析,抽象出满足上述要求的浪形函数的通式和对应特定浪形的具体表达式。There are varied buckling modes of cold rolled strip caused by the unequal residual stress distrlbution.To solve the buckling problem needs to define reasonable original displacement functions. On the other hand, the automatic flatness control also bases the shape thoery, With the BLD-90 laser detector, an exact measurement has been done, and a polynomial least squares surface fitting was made to abstract wave functions including a general formula and every specific expression.
